A brief overview of the black-box behavioural modelling of electronic circuits for transient simulations

Transient simulations of electronic circuits in the time domain can be one of the most complex tasks that engineers encounter in the field of electronics and microelectronics due to two main problems: slow speed of SPICE transistor level circuit simulations and limited accuracy of classic techniques for improving speed of circuit simulations. The black-box approach to behavioural modelling of electronic circuits, although very challenging, is particularly interesting due to possibility of fast and accurate simulations and that is the reason why black-box modelling techniques are gaining more and more attention in industry and academic community. The goal of this professional paper is to give a brief overview of the topic, identify current state-of-the-art and give suggestions for the future research in the area of black-box behavioural modelling of electronic circuits in the time-domain.
